The number of people being recalled to prison after they’ve been released has nearly doubled in recent years. It has come at a significant cost to the public – but has it made the public significantly safer? Most recalls aren’t for further offending. Could the gains made by the early release scheme be undermined by the huge number of people being recalled to prison?

Former prisoner and filmmaker Chris Atkins investigates the opaque world of prison recalls. He speaks to prison reform charities who say arbitrary recalls drag many further into a cycle of crisis and crime and follows one troubled prisoner over five years, who is recalled four times despite never being charged with any new crimes.

Fishermen from the Philippines, Ghana and Sri Lanka speak out about how badly, they say, they were treated by a Scottish fishing company that hired them. Most of the fishermen have been waiting in the UK for more than 10 years for their case to be heard. Despite two extensive police investigations, no convictions have been secured for human trafficking or modern slavery. This is the first time the fishermen have spoken out.

Over three decades, a priest assessed as posing a risk of “significant harm” to children and vulnerable people worked in the Church of England. But allegations against him didn’t stick, leading to him remaining in post until after he was offered a substantial pay-off. The surprising manner in which he finally left in 2022 raises serious questions about the judgement of Church leaders.

Camp Lejeune is a vast US Marine Corps base in North Carolina. It’s been in operation since the 1940s and covers a massive 240 square miles. But for years it hid a secret. For decades, its water supply was contaminated with harmful chemicals found to increase the risk of some cancers. It’s estimated that one million people might have been exposed to the toxic water.

But it wasn’t just American personnel who were based at Camp Lejeune. Soldiers from all over the world - including from the UK - also spent time there on training exercises and exchange programmes.

Emma Forde hears from the British veterans and their families who lived and worked on the base and have since suffered serious health problems or seen loved ones die from conditions associated with exposure to the water. But despite a compensation scheme for victims being widely reported in the US, there are concerns that those from the UK are still unaware of the serious health risks they were exposed to. And time is running out.

Project Rescue Children claims to save children from trafficking and abuse, but the BBC has uncovered evidence of false and misleading social media posts. The charity's director, Adam Whittington, has raised thousands of pounds from sponsors and donors around the world. But the BBC has found that unsuspecting children are being used as props, and the rescue centres have no children. Project Rescue Children rejects the BBC's findings and says its work has benefitted hundreds of children worldwide.

There are more empty homes than homeless households in this country. Why?

Filled with cobwebs, windows broken, and rats scurrying about in their overgrown gardens, the UK has hundreds of thousands of ghost houses - properties where no one lives. The UK also has the worst homelessness problem in the rich world. So could we use those empty homes for the people in dire need of a home?

Simon Maybin investigates the phenomenon of empty homes and, over nine months, follows the work of someone trying to turn unused properties into homes for families among the record numbers who are now homeless.
